I'm having following view page,
#using (Html.BeginForm())
{
<fieldset class="fs">
#foreach (var item in Model.lstTravelReadyEntities)
{
<label class="Detail1"><b>Associate Id : </b>#item.Var_AssoId </label>
<label class="Detail1"><b>Vertical :</b>#item.Var_Vertical</label>
<label class="Detail1"><b>Visa ValidFrom :</b>#item.Dt_VisaValidFrom </label><br /><br />
<label class="Detail2"><b>Associate Name :</b>#item.Var_AssociateName</label>
<label class="Detail2"><b>Account Name :</b>#item.Var_AccountName</label>
<label class="Detail2"><b>Visa ValidDate :</b>#item.Dt_VisaValidTill</label><br /><br />
<label class="Detail3"><b>Grade HR :</b>#item.Var_Grade</label>
<label class="Detail3"><b>Project Name :</b>#item.Var_Project_Desc</label><br />

I want pass all the values of this view page to the controller as parameters for inserting these values into the new table.How can i Achieve this?
Use #Html helpers for your controls.
Have a look at this blog entry from Scott Gu. It's about MVC2 but still applies to MVC4.
For a more concrete example, have a look at this question regarding #Html.RadioButtonFor().
Also, I would recommend hooking your events using jquery instead of inline onclick= html attributes.
<script type="text/javascript">
$("form radio").click(function(){ // or whatever selector you need
Getfunc($(this)[0].value);
});
</script>
Finaly, you will need to make sure your #Html.BeginForm posts to an [HttpPost]-decorated action on your controller that takes your Model as parameter.
What is the Problem in Existing code ?
There is no Input Type Text Control in the form and that's the reason information is not being sent to server. TextBox like controls forwards the data for sending the information to Controller Action Method.
Corrective Action
Let's say TextBox is not Required in you case. Then, you can place Hidden Fields for those View Model Properties which are required to be sent to Controller Post Action method.
Example
#using (Html.BeginForm("ActionName", "ControllerName", FormMethod.Post))
{
<fieldset class="fs">
#foreach (var item in Model.lstTravelReadyEntities)
{
<label class="Detail1">
<b>Associate Id : </b>#item.Var_AssoId
</label>
#Html.HiddenFor(i=> item.Var_AssoId) //Added Hidden Field to send this to server
<label class="Detail1">
<b>Vertical :</b>#item.Var_Vertical</label>
#Html.HiddenFor(i => item.Var_Vertical) //When post this Hidden Field will send
<label class="Detail1">
<b>Visa ValidFrom :</b>#item.Dt_VisaValidFrom
</label>
#Html.HiddenFor(i => item.Dt_VisaValidFrom)
<br />
}
<h2>
Response Details</h2>
<br />
</fieldset>
}
For explaining point of view, I excluded some of the controls. Now, You can add Hidden Fields for those Properties which are required to be sent to Action Method.
Also you should use View Models instead of Passing Individual parameter to Action Method.
Hope this will help you.
Hi try like this,

I have a ToDo items dashboard page where I display the ToDo's, their status and some other app info.
I want to have one input where I can add a string value (the ToDo title) and on the button click
have that passed to the controllers Create get method, so it populates the Create views Title input field with that value.
I want to it without a form if that is possible as the dashboard page already has a model which is an IEnumerable, just pass that value as a querystring parameter to the Create pages get view (or is it doable in javascript?).
Im not an MVC expert and also not as familiar with the new tag helper methodologies. Any help in how to structure thiswould be helpful.
Here is the html
<!-- Add Task -->
<div class="input-group input-group-lg">
<input class="form-control" type="text" placeholder="Add task and press enter..">
<span class="input-group-addon">
<a asp-controller="ToDoItems" asp-action="Create" ><i class="fa fa-plus"></i></a>
</span>
</div>
<!-- END Add task -->
here is the new model
public Class MyModel{
public IEnumerable<your old model> Old Model {get; set;}
public string Title {get;set;}
}
You can create a form like so in html with razor syntax
#model MyModel
...
<form action="/Controller/PostTitle/" method="post">
#Html.TextBoxFor(m => m.Title,new {#class = "...", #placeholder="...",
#requried="required"})
<input id="export-btn" type="submit" value="Download" class="btn btn-info" />
</form>
The #TextBoxFor will create a textbox and the lambda lets you use your strongly typed model.
Here is the controller
[HttpPost]
public IActionResult PostTitle(string Title) {
...
}
Here am pressing the pay button i have to pass ids and the form data
in my view am displaying some data using for each loop,and when i click a button i have to pass the number of ids which returns in model class and some form data(which is outside the model class) to the controller,i have tried my maximum,But i failed,please help me to make this?
view.cshtml
#foreach (var item in Model) {
<input type="hidden" value="#item.vid" name="abc" />//i need these ids in my controller
<tr>
<td>
<td> #Html.DisplayFor(modelItem => item.vid)</td>
.........
...........//some more displaying
}
#Html.BeginForm("makepayment","home",FormMethod.Post)
{
<h3>Card Holder Name</h3>
<input type="text" name="cname" />
<h3>Account Name</h3>
<input type="text" name="number" />
<h3>CVC</h3>
<input type="text" name="securitycode" />
<h3>Expiery Date</h3>
<input type="text" name="expdate" />
<input type="submit" id="sub" name="sub" value="pay" />
}
controller
public ActionResult makepayment(FormCollection values,????)
{
......
.......//codes
}
i know i may have to use array or something,but i dont know how,somebody please help
Now, following semantics, you should create a separate viewmodel class that can hold such information, but that is not always the case.
So here is my understanding. You have a model class which you are what your form consists of, but you also want to send the ids that are just related to something else. In you post action, you get an instance of your model class with model binding.
//Please ignore the [] chars
public ActionResult makepayment([Name of you model class] modelInstance)
{
//modelInstance will contain the fields of the model.
//The remaining field, you can access using.
//Request.Form["{name of the input field}"]
var id = Request.Form["abc"]
}
Hope this helps you out. Otherwise, hit me with up and we can easily go through it in more detail.
P.S :- I am not a sir.
I have a 'Survey' page which is declared as follows:
#using (Html.BeginForm("Survey", "Home", new { questionList = Model.Questions }, FormMethod.Post))
{
<div class="survey">
<ol class="questions">
#foreach (Question q in Model.Questions)
{
<li class="question" id="#q.QuestionName">
#q.QuestionText<br />
#foreach (Answer a in q.Answers)
{
<input class="answer" id="#a.DisplayName" type="checkbox" /><label for="#a.DisplayName">#a.AnswerText</label>
if (a.Expandable)
{
<input type="text" id="#a.DisplayNameFreeEntry" maxlength="250" /> <span>(250 characters max)</span>
}
<br />
}
</li>
}
</ol>
</div>
<div class="buttons">
<input type="submit" value="Finish" />
</div>
}
When I'm stepping through my code, it hits the method I've set up to process their survey:
[HttpPost]
public ActionResult Survey( List<Question> questionList, FormCollection postData)
{
//Process Survey
}
However, when I step through I am finding that the variable questionList is null and the variable postData does not contain any data from the Form. Trying to access checkboxes via Request[a.Displayname also does not work.
Everything I've read indicates that this is the correct way to persist values from the Model to the submission method, and that I should be able to access the FormCollection this way.
What am I doing wrong?
You have to save questionList as a hidden field on the page. Non-primitive types do not get persisted simply by passing them in.
One way you can do that is
#Html.HiddenFor(m => m.Foo)
Or you could do it directly in HTML like this
<input type="hidden" name="Var" value="foo">
where m is your model.
The fact that the postData is empty is weird, since every input element with id inside a form tag should be passed with the POST request.
But the questionList won't be received that way, since its a list of complex class (not just a string or int), and the default ModelBinder (the thing that turns the HTTP Request Variables into parameters passed to the action method) don't support lists of complex classes.
If you want to be able to receive List you will have to implement your own binding mechanism with CustomModelBinder.
This article can help you implement it.
One problem is your checkbox and your textbox are not properly bound to your model.
You should be using #Html.CheckBoxFor and #Html.TextBoxFor
I'm using MVC with Razor and C#. I would like to update an element... a counter with ajax. Here is my code:
#model Domain.CounterObject
#using (Ajax.BeginForm("Count", "CounterObject", new AjaxOptions { HttpMethod = "POST", UpdateTargetId = "my-control" }))
{
<div id="my-control" class="bid-object">
<div>
<span class="title">#Html.Encode(Model.Title)</span>
</div>
<div>
<span class="display">#Html.Encode(Model.GetFinalDate())</span>
</div>
<div>
<span class="display">#Html.Encode(Model.GetValue())</span>
</div>
<div>
<input type="submit" value="Count" />
</div>
</div>
}
In my controller I have this code:
[HttpPost]
public PartialViewResult Count(CounterObject counter)
{
// Special work here
return PartialView(counter);
}
The problem is that my CounterObject counter I receive in my Count method is always null. How can I pass a value from my page to the controller?
I receive in my Count method is always null
First of all you are not submitting anything from the form then how does the binding happens?
If the user is not allowed to edit the values but still you want to submit them through the form then you have to use hidden fields along with them.
For ex.
<div>
<span class="title">#Html.Encode(Model.Title)</span>
#Html.HiddenFor(m => m.Title)
</div>
Note that the hidden fields should have the same names as the properties to make the binding happen successfully.
It is better to have properties in the Model that store the GetFinalDate() and GetValue() results so you can easily bind the things like in Title.
You'll have to define a input field with a name and id that the ModelBinder can then Bind to your CounterObject.
You could use #Html.EditorForModel once and then inspect the generated Html to see what kind of name/id pairs it is generating. With those you can go on and handcraft your Html if you wanted to.
use
<span class="title">#Html.Encode(Model.Title)</span>
<div class="editor-field">#Html.EditorFor(Model => Model.Title)<div>
//For other fields
In this way you can bind to your object.
Still kind of new to MVC, so please bear with me. I'm trying to grab some dynamically generated HTML. In this case, list items in my notifyList. I plan on looping through each one in the controller and adding them as database entries. Any help is appreciated, thanks.
View
#model _BaseViewModel
// The form it's within...
#using (Html.BeginForm("Create", "Leaf", FormMethod.Post, new { id = "createForm" }))
<div class="editor-label bottom-area bottom-header">
Notification List:
</div>
<div class="editor-field bottom-area">
<ul id="notifyList"></ul>
</div>
Controller:
[HttpPost]
public ActionResult Create(_BaseViewModel model)
{
// Some loop here
// get html here
db.UserItems.AddObject(model.user);
db.SaveChanges();
//
return RedirectToAction("Index");
}
As far as I understood, you use jQuery to fetch <li/> elements into notifyList. What you need to do here is to generate a hidden input as well. Sample:
$("#btnAppend").click(function() {
for(var i = 0; i < 4; i++) {
var _val = "Foo " + i;
var $li = $("<li/>").text(_val);
var $hidden = #("<input/>").
attr("type", "hidden")
attr("name", "foo").
val(_val);
$hidden.appendTo($li);
$li.appendTo("#notifyList");
}
});
This code will generate following output inside your DOM:
<ul id="notifyList">
<li>Foo 0<input type="hidden" value="Foo 0" name="foo" /></li>
<li>Foo 1<input type="hidden" value="Foo 1" name="foo" /></li>
<li>Foo 2<input type="hidden" value="Foo 2" name="foo" /></li>
<li>Foo 3<input type="hidden" value="Foo 3" name="foo" /></li>
</ul>
When you make a http form post, you can grab the values by the below controller action implementation:
public ActionResult Index(string[] foo) {
foreach(var item in foo) {
//Work with each individual item
}
//continue your code
}
it doesn't work this way. html only exists in the view. the controller has no concept of html (not should it). data sent to the controller comes in 1 of types (GET, POST). there are others, but these are the main to.
get is typically associated with the querystring www.domain.com/mypage.aspx?key=value
where post is the input values from form
<form action="mypage.aspx" method="post">
<input name="key" value="value"/>
<input type="submit" value="click me"/>
</form>
So adding items to a html list won't provide any meaning to the controller. javascript and ajax provide more options on how the data gets sent to the server, but the data is sent, not the markup. and the data is sent as key value pairs.
